[net,0/2] wireguard patches for 5.18-rc4

Hi Davekub,

Here are two small wireguard fixes for 5.18-rc4:

1) We enable ACPI in the QEMU test harness, so that multiple CPUs are
   actually used on x86 for testing for races.

2) Sending skbs with metadata dsts attached resulted in a null pointer
   dereference, triggerable from executing eBPF programs. The fix is a
   oneliner, changing a skb_dst() null check into a skb_valid_dst()
   boolean check.

Thanks,
Jason

Missed the PR, sadly. Paolo was handling it and he's on EU time.
